If I do 'rtifconfig rteth0 up' on a network with heavy broadcast traffic
(which I later intend to catch/throw away), the system does a hard
lockup after a few lines like these:
'RTnet: no one cared for packet with layer 3 protocol type ...'
I would humbly suggest something like the attached patch.
Regards
Anders Blomdell
